Specification of Letters Patent.

Application led December 2, 1907. Serial No. 404,852.

To all 'whom it may concern.' i i Be' it known that I, ROBERT A'. B.'lVaLsi-r a citizen of the United States, residing at St.. Louis,Missouri, have invented a certain new and useful Improvement inApparatus for Making Wire-Glass, of which the following is a full,cleai',`a1id exact description, such as will enable others skilled 1nthe artto which it appertains to make and use the same, reference beinghad to the accompanying drawings, forming part of this specification. invvhichy Figure 1 is a side elevation of an apparatus embody-ing thefeatures of my invention; and'Fig. 2 is a. view similar to Fig.- 1 vbutshowing the parts of the appaz ratus in a different position.

described.

This invention relates to the manufacture of Wire glass and has for-itsobject to provide an apparatus for practicing the method described in mypending application Serial No. 401,851, filed December 2, 1907'.y

l The method described in my application above -referred Ato consists in-forming a sheet of Wire glass from three separate layers of glass.between two of which a`Wire mesh is interposed, said layers beingWelded together while they are in a heated condition sc as to .produce asingle sheet.`

Referring to the drawings which illustrate, the apparatus which formsthe llsubject of the present invention, 1 designates -a table abovewhichv a smooth surface roller 2 is arranged, said roller being adaptedto beA raised or elevated for a purpose hereinafter A smooth surfaceyroller 3 is also arranged above the table and intermediate thel rollers2 and 3 is a smooth surface roller 'twhich ism-ranged ab'ovethe table adisthe thickness of thefinished tance equal to product. G.

To form a sheetof wire glass with an apparatus of this description .Ifirst dump a batclrormass of molten glass onto the table and then movethe table in the direction of vthe arrow in Fig. 1, the roller 2,spreading the mass of glass 5 over the table to forma i bottom layer (i.When the end of the layer G has arrived at a point adjacent the roller 3a second mass 7 of molten glass is dumped onto said layer so that theroller 3.4will spread a portion of said mass over the bottom layer toform a'sccond layer 8. The end of a piece of Wire mesh 9 is placed onthe bottom'layer 6 prior to the operation of dumping the massyof moltenglass 7 onto said layer so that said mesh will be covered by the secondlayer at the same -time said layer is being formed.v After the first andsecond'layers have been formed and the Wlre mesh has been arrangedbetween them, the 'mesh 1s severed from the source of supply and thetable is moved in' the opposite direction, as indicated bythe 'arrow inFig. 2k so that the roller 4 will 'spread' the remaining portion ofthemass second layer Was completed and bef re the table started to move inthe direction of the "i arrow in Fig.'2. As the Wire mesh is c0111-,

pletelygcovered by the lass which forms the er, said mesh willnot/oxidize as second it is no exposed to the air after it has bef comeheated from contact with the molten glass so that said mesh will lookbright and new in the finished prodnct or sheet of glass. The wire meshhas .atendencyl to contract 'and draw the glass in W'lrchait is4errrbedded and this produces an` irregular oruneven surface on thesecond layer, butthlsuneven surface is covered. by the third layer orfinishing layer, so that the n'ished product' has a smooth and brillianturface. 'Pref` erably the third layer, or -n Shing layer, is. not asthick as the first andfsecond layers but is merely in the form of a comaratively thinl coating that fills in the irregu arities in the secondlayer. If desired the end of the Wire mesh can be placed underneathv theroller 2 as shown in dott-ed lines in Fig'. 1 prior to' the operation ofdumping the mass of glass 5 onto the table sogas to cause' said rollerto force'the Wire mesh into the bottom layer' simultaneously with theoperation of forming said 1ayer. It is preferable howcver,to introducethe Wire mesh in the manner shown in full lines in Fig. 1.

H'avinr thus'described my invention, Whatp I claim 1s:-

ihass of molten glass/over said bottom layer,

and a thirdf roller arranged intermedifite the rollers previouslyreferred to for spreadingthe remaining portion` of said second mass ofmolten'glass over the second layer toform a finishing layer ot* coatingfor the `sheet of l glass; substantially as described.

2. An apparatus for forming a sheet of glass comprising a table, -anadjustable roller arran ed above the table for forming a mass of mo tenglass -into a botgtoin layer, -and a pair of rollers arranged aove the-table and so dis osed that the' 'will 4spread one ortion o a 4mass ofmo ten glassover the ot# tomlayer toform E second layer when the table'is niov'edin lone direetlon and then spread the remaining portion ofsaid mass over-the second layer to form a finishing. layer when thetable is moved inthe-0ppm v site direction; substantially as describedi1- Inttestimon whereof I hereunto aix'my signature in .t e resence oftwo'wtnesses,

` this twenty sixth ay of November 1907.
